Dragino DR-ORP1 ORP (Redox) Probe – RS485, IP68

The Dragino DR-ORP1 is a rugged ORP (redox) probe used to measure oxidation-reduction potential in water. ORP is widely used as a practical process and trend indicator—it helps operators understand whether water chemistry is moving toward a more oxidizing or reducing state, and it’s often paired with other parameters to keep treatment and dosing stable. The probe is designed to connect to Dragino WQS-LB or WQS-NB water quality nodes and outputs readings via RS485 for reliable long-term installations.

Common industries and real-world use cases:

Drinking water & swimming pools: Verifying disinfection effectiveness, typically alongside chlorine or ozone values, and spotting rapid changes that may require adjustment.

Wastewater treatment: Process control and monitoring treatment stages where redox conditions matter, helping detect shifts in the treatment process.

Aquaculture & environmental monitoring: A general water quality trend indicator for ponds, tanks, and natural waters where stability is key.

Industrial water circuits: Monitoring chemical conditions and supporting corrosion/process oversight in cooling loops and industrial water systems.

Technically, the DR-ORP1 uses a high-purity platinum electrode and provides a wide ORP range of -1999 to +1999 mV with 1 mV resolution and ±3 mV accuracy. Automatic temperature compensation helps keep measurements consistent under changing conditions. With IP68 protection, 0.6 MPa pressure resistance, and a 5 m cable, it’s built for direct in-water, long-duration deployments.
